Things are badly backed up right now in the back end. Keep an eye on CityStrides and try the single-activity sync request after the Activity Processing Delay gets down into single-digit hours for all members.
I missing one activity from yesterday that I ran while the website was down. I have a feeling thatās why it isnāt syncing as this morningās active synced from Garmin right away. I tried to manually sync yesterday through settings, but that doesnāt seem to be working. Hereās the activity link: Garmin Connect
Can you try that single activity sync attempt again (if itās not already present)?
